FS#65 - .desktop files, be nice if they included the non-english info as well

Tags:

.desktop files only include the English stuff right now (using the .desktop default tags.)
Be nice if in addition to 'title', we also include 'title[de]' type extras, whatever is in the PXML.xml
pnd_pxml_t includes all the goods, but pnd_disco_t has only the summarized english stuff.
